100
What is absorption?
What is a process that allows us to see objects that do not produce their own light?
100
What is convection?
What is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat?
100
What is mechanical energy?
What is is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object?
100
What is radiation?
What is the emission of energy as electromagnetic waves or as moving subatomic particles, esp. high-energy particles that cause ionization?
100
What is sound energy?
What is the form of energy associated with the vibration or disturbance of matter. Sound is a mechanical wave and as such requires a medium to travel through.
200
What is chemical energy?
What is energy stored in bonds between atoms in molecules?
200
What is electrical energy?
What is the electric potential as follows: The electrostatic potential energy, UE, of one point charge q at position r in the presence of an electric potential is defined as the product of the charge and the electric potential?
200
What is medium?
What is the intervening substance through which impressions are conveyed to the senses or a force acts on objects at a distance?
200
What is reflection?
What is the throwing back by a body or surface of light, heat, or sound without absorbing it?
200
What is wave?
What is move one's hand to and fro in greeting or as a signal?
300
What is a circuit?
What is a roughly circular line, route, or movement that starts and finishes at the same place?
300
What is energy?
What is power derived from the utilization of physical or chemical resources, esp. to provide light and heat or to work machines?
300
What is nonrenewable resource?
What is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years?
300
What is refraction?
What is the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density?
300
What form of energy requires a medium through which to travel?
What is sound?
400
What is conduction?
What is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material?
400
What is heat energy?
What is energy in transit due to a temperature difference?
400
What is nuclear energy?
What is the energy released during nuclear fission or fusion, esp. when used to generate electricity?
400
What is a renewable resource?
What is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere?
400
A purple object absorbs all colors of light except for?
What is purple?
500
What is conservation of energy?
What is a principle stating that energy cannot be created or destroyed, but can be altered from one form to another?
500
What is kinetic energy?
What is energy that a body possesses by virtue of being in motion?
500
What is potential energy?
What is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors?
500
What is solar energy?
What is radiant energy emitted by the sun?
500
When you go outside on a sunny day, you might feel heat from the sun on your skin. What type of solar energy is this?
What is infrared radiation?
